Hi! Sorry to hear the Northern Train Tickets & Times app won’t open on your iPhone running iOS 18.6.2. Let's try to get this sorted out together.

To start, can you tell me if you see any error messages when you try to open the app? Also, have you tried anything already, like restarting your phone or reinstalling the app?

Meanwhile, here’s a step-by-step guide to troubleshoot the issue:

1. Close and Reopen the App:
Sometimes apps get stuck. Double-click the Home button (or swipe up from the bottom on iPhone without a Home button) to see your recent apps. Find the Northern Train Tickets & Times app and swipe it up to close. Then try opening it again.

2. Check for App Updates:
Open the App Store, tap your profile icon at the top right, and scroll to see if there’s an update available for the Northern Train Tickets & Times app. An outdated app may not open properly.

3. Restart Your iPhone:
A simple restart can clear temporary glitches. Press and hold the side button and either volume button, then slide to power off. Turn your phone back on and try opening the app.

4. Reinstall the App:
If the app still won’t open, try deleting it and reinstalling:
- Press and hold the app icon until it jiggles, then tap the ‘X’ or ‘Remove App’ option.
- Go to the App Store and download it again.

5. Check Internet Connection:
Make sure you have a stable internet connection. Try switching between Wi-Fi and mobile data to see if that helps.

6. Check for iOS Update:
Although you’re on iOS 18.6.2, it’s good to check if there are any updates: Go to Settings > General > Software Update.

If none of these steps work, the problem might relate to app compatibility issues or a bug. In that case, a temporary workaround can be to use the website via your browser until a fix is available. You can also reach out to Northern Rail’s support team at [email protected] for further assistance.

Let me know how these go or if you see any specific error messages while opening the app! Are you satisfied with the solution I provided?
